application mea october 5, 1925. serial No. 60,433.

This invention relates to faucets and is in the nature of an improvementon thefaucet illustrated and described in U. S. Patent No. 1,564,589,issued to me December 1, 1925. v The object of my improvements,generally stated, is the perfecting of the faucet disclosed in thepatent above referred to for the purpose of lessening cost ofmanufacture, rendering the valve and parts associated 1U therewith morereadily accessible for renewal and repair, and to afford a convenientlycontrolled self-closing faucet which is peculiarly eflicient inoperation.

The invention is illustrated in the accompanying drawing-showing 'inlongitudinal vertical section a faucet embodying 4my improvements.

According to the present invention the faucet is formed' with asubstantially cylindrical hollow body 1 having at its lower end, aninlet openings 2, located axially of the body, and communicating throughsaid inlet with a tubular element 3 which is adapted to be secured to aliquid supply pipe, not shown. y

Above its inlet 2, the body is provided in its peripheral wall with anoutlet 4 opening into a spout element 5. The elements 3 and 5 abovereferred to and the body 1 are, by preference, I:ast in a single piece.Said body 4is formed interiorily with two vertically spaced apartchambers 6 and 7, preferably circular in horizontal sections, separatedby an apertured partition 8 which is located below the level of thebottom of the outlet 4 into said discharge spout.

Above said outlet the inner periphery of the chamber is screw threadedas at 9.

Mounted upon the open upper end of the faucet body 1 is a cap member 10havingan upwardly extending portion 11 which is externally screwthreaded, and a downwardly extending portion 12 provided with screwthreads engaging the internal threads 9 of the body to separably couplethe cap thereto.

Formed integral with said cap and depending from its extension 12 is acylindrical cage, indicated generally by 13, having at its lower end acircular flange to make a nonleakable joint at 14 with the partition 8.Extending from said cage through ,the aperture of said partition intothe chamber 7 is a cylinder 15 having an open lower end 16 terminating ashort distance above the chamber fioor 17 havingtherein'the inletpassage 2.

From its lower end theV cylinder 15 is bored, as at 18, upwardly to aperipheral diameter of the cylinder isless than the divameter of thechamber 7 thereby affording an annular channel 21 which communicateswith the cylinder bore 18 through peripheral ports 34 provided in thecylinder below the elevation ofthe valve seat 19. The cap, cage andcylinder, it is to be noted, constitute 1n its entirety a core which isremovable as a l single piece from the body.

The valve 20 consists of apiston fitted for axial movement in thecylinder bore 18 to serve as a closure for said ports,l said valve is,furthermore, provided at its upper end with a surface 22 adapted to makea tight closure with the seat.19.

Said valve is provided with stem/ 23 'ex- 75 tending axially through thecage 13 into a i hole 24 provided in the cylindrical lower end of anoperating member 26, the ,operating member having a stem 27 to which issecured a handle 28 as by means of a headed screw 2,9. Said operatingmember is provided with external screw threads 3() engaging screwthreads, as 31, provided interiorly of the cap; such interengagingthreads being of a pitch sufficient to enable service pressure of water,or other liquid, acting upwardly against the valve to eect endwisemovement of the operating member 26 permitting the valve 20' to closeagainst its seat.

. The endwise movement above referred to which occurs to the operatingmemberv during the closingtravel of the valve turns the operating memberin one rotary direction, hence Aby employing the handle 28 to turn saidmember in the opposite rotary direction the valve is compelled to openwith respect to its seat 14 and the ports 34. As hereinbefore explainedthe piston valve is fitted within the cylinder bore 18`and the valvestem 23 extends into the hole 31v of the op- 100 erating member 26 and,in consequence, the valve is guided axially of the body by boththecoreand .the operating vmember which is movable with the valve inboth its opening and closing movements. 23S-.represents 1 0 5 agland-nut taking on the screw threads of the core portion 11, Said nutserving as af housing for packing (not shown) provided above a washer 32which is seated upon the top of the-cap, said washer serving' asa re-110 movable partition to pre-vent the packing following the operatingmemberv when the latter is actuated to unseat the valve.

The operation of the invention is as ,fol-1 lows: The valve 20 is heldnormally against its seat by means of liquid pressure actingl`v Vhen'the the cylinder bore above the valve, whence it escapes through thecage 13 to the discharge spout .5. What I claim, is,- 1. A faucetcomprising, in combination, a body member having an inlet opening in thebottom thereof and an outlet in its side,4

said body being provided interiorly with an apertured partition, aninteriorly screw t threaded core member extending into the body andthrough said partition, said core being provided with a cage elementabove said partition and a cylinder provided with ports in itscircumferential Wall below said partition, said cylinder having avalveseatf ing surface in the upper portion of its bore, a

piston-valve within said cylinder, and manually operable means foreliecting'the opening movement of the valve, said means being providedwith externalfscr'ew threads engag-A ing in the screw threads of thecore, said screw threads being of a pitch sufficiently long to enable apressure of liquid acting axially lagainst the valve to effecttheretraction of said meanstozpermit the' closingA of the valveagainstits seat' t 2. A faucet comprising, combination, a

body member said body member being ro vided with ali apertured partitiondividing the interior of the body linto two 4chambers, a core memberextending into the body member and through the aperture of the partition, said core member being formed below vthepartition with a boredcylinder element open at its lower end, said cylinder being -of adiameter to provide an annular channel between the same andtheperipheral wall of the surrounding chamber, ports provided in theperipheral wall of the cylinder and communicating with said channel, a

`piston provided vin the cylinder bore and serving as a valve withrespect to`said ports, a stem for said piston, an operating memberhaving screw threaded connection with said core, said operating memberhaving a hole therein to'receive said stem and cooperating withthecylinder bore to guide the iston.

3.' A" faucet comprising, in com ination, a body member, said` bodymember being provided with an apertured partition dividingtheinteriorfof the body into two chambers, a` core member extending intothe body member and through the aperture of the partition, said coremember being formed below the partition with a bored cylinder elementopen at its lower end, said cylinder being of a diameter to provideanannular channel between the Same and the wall .of the surroundingchamber, ports provided in the peripheral wall of the cylinder andcommunieating with said channel, a piston provided in the cylinder boreand serving as a valve with respect to said ports, a stem for saidpiston,'an operating member extending into said core, said operatingmember having a hole therein to receive said stem and coo erating withthe cylinder bore to guide tEe piston.
